use and has for its object to provide an 1mproved construction -for apipe whereby any` obstruction atthe bottom of the bowl at its junctionwith the smoke passage may, be easily, quickly and positively removed. Afurther but subsidiary object of the invention is to provide a device,permanently associated with or carried by the pipe, which may be used incoperation with the improved structural features ofthe pipe proper tosecure the result specified.

One of the problems of the pipe user is to: revent` clogging or stoppageof the pipe owl and bore or smoke passage, especially where the latterenters the former, thereby insuring that the pipe shall .draw well, andvarious constructions have been suggested to realize this ideal ingreater or less degree. Others again have not attempted to prevent thediiiiculty but have directed their efforts t0 providing a Way foreffectively clearing the pipe when obstruction has taken place.

My invention, herein to be described, be-

longs to the last class rather than to the It is a matter of commonexperience with pipe smokers that a pipe soon tends to clog at thebottom of the bowl at the point where the stem bore or smoke passageenters. The material which does, the clogging is a mixture of tobaccoand ash more or less saturated with saliva and nicotine, and takes theform of a hard baked mass called dottle This dottle usually occupies thebottom of the pipe bowl at the point mentioned and extends up into thebore of the pipe for a short distance, thereby becoming, so to speak,locked into place.

To remove this dottle the smoker thrusts a pipe cleaner, wire, hat orhair pin, or similar device, down the smoke passage into the bowl. Evenwhen these devices are at hand their use is disagreeable and dirty. Morecommonly, the smoker inserts a knife blade into the bowl and endeavorsto push the dottle away with the knife point.

' with; Fig. 3 represents a section taken along the line 3--3 of Fig. 1;Figs. 4 and 5 represent views, similar respectively to Figs. 5 and 4, ofa pipe provided with a modified form o-f my invention; and Fig. 6represents a section taken along the line 6-6 of Fig. 4. p In thedrawings, which show (referring particularly to Figs. 1 to 3) theapplication of my invention toa very usual form of briar pipe, 1 denotesthe bowl of the pipe and 2 a'short shank integrally united to the.

b owl and having a smoke passage or bore 3 opening into the bottom ofthe bowl at one side as at 4. The usual bit 5, of greater or lesslength, is fitted to the' outer end of the stem.

The shank 2, on its bottom adjacent to the bowl, is preferably scoopedout or recessed, as shown at 6. Preferably this recess is given the formof a transversecylindrical segment. They recess also referably does notextend to or open directly into the bore 3. From the top of the recess ashort straight passage 7 connects with the end of bore 3 as it opensinto the pipe bowl.

A metal sleeve 8 having an opening 9 is mounted upon the shank 2adjacent to the bowl, being preferably fitted upon an inner bearingsleeve 8 having flanged ends, and is adapted to be rotated to bring theopening either in or out of registry with the recess 6. The flangedbearingsleeve 8 must, of course,

itself have an opening in registry with the y recess 6.

The sleeve 8, diametrally opposite openbe finished in any desired way,as, by plating, or may be of gold, silver, or other metal.

They may, therefore, be made to add to the finish and richness of thepipe as a whole. In use, should a dottle form in the usual lWay, thesleeve '8 is turned ,thumb until the opening 9 is in registry by lingerand with'the recess 6. The pin 11 is then withdrawn by the aid of head12 and thrust up through the passage 7 thereby dislodging the shorterthan the inner bearing sleeve 8. The

l passage 7 is continued along the bottom of within the sco e of theinvention and of the the stem as an open slot and the bearing sleeve isalso provided with a slot in registry therewith. The pin 11 has itsouter end fixed in the sleeve 8 and passes through the slot in thebearing sleeve and into passage 7 'where it normally lies in theposition shown in Fig. 4 with its inner end just 1nside the smokepassage adjacent to the bowl. Preferably this inner end is provided witha Small ball tip.

By sliding sleeve 8 tow-ard the bowl, the pin 11 will be thrust upwardlythrough the passage 7 so as to push the dottle into the bowl in the samemanner as has been previously-described in the oase of the pipe shown inFigs. 1 to 3. Pin .11, lying permanently in the passage 7 serves as afeather to prevent the sleeve 8 from rotating upon its bearing sleeve.

Various changes in detail may be made claims which ollow and will .beobvious to those skilled in the art. Thus the sleeve 8,.

instead of being arranged rotatably, as shown, may be made to moveaxially so as to uncover theirecess 6 when desired, the opening 9 beingomitted; the bearing sleeve 8 would, in such case, have to be madelonger, of course, or other ways of o ening or closing the recess 6 andpassage may be employed.-

The recess 6 may be omitted altogether, if desired, letting the passage7, in such case, extend clear through to the outer surface of the shank.

And, of course, any pin or slender stick such as a match stick or thelike, may be substituted for the pin 10.

The cleanincgl passage 7, being downwardly directe serves also as adrainage well for the `fluid saliva residues and the like which usuallycollect inthe bottom of the bowl. This residue may be removed altogetherbymoving the sleeve 8 so as to open the cleaning passage exteriorly andthis .removal may then be facilitated by blowing into the upper end ofthe smoke passage while the open ,end of the bowl is closed bythe palmof the hand.

The adaptation 4of my invention to other forms of pipes will be obviousto those -skilled in the art.

- Ibowl, said cleaning edto be Having described my invention I claim:

1. As a new article of manu acture, a smokers pipe comprising a b owland shank portion joined thereto, the latter having both the usual smokepassage and a cleaning passage leading upwardly to enter the smokepassage adjacent its opening into the bowl, said cleanin passagebeingdirected so that a match stlck entered therethrough will act to`loosen the dottle and' thrust it into thebowl.

2. As a new article of manufacture, a, smokers pipe comprising a bowland an in-v tgral shank portion, the latter having both the usual smokepassage and a cleaning passage leading upwardly to enter the. smokepassage adjacent its opening into the passage being directed so that amatch stick entered therethrough will act to loosen the ottle and thrustit into the bowl.

3. As a new article of manufacture, a smokers ipe comprising a bowl andshank portion joined thereto, said shank being provided with twoindependent passages which open into the l.bowl at a common point, theoutlet of one passage being at the outer end of the shank whereby asmoke passage is-formed and the outlet of the other passage being at thebottom of the shank wherebyv a cleaning passage is formed adapted to beentered by a match stick so as to loosen and thrust the dottle into thebowl.

4. As a new article of manufacture, a smokers pipe comprising a bowl andshank portion joined thereto, said shank being provided with twoindependent passages which opcn into the bowl at a .common point, theoutlet of one passage being at the outer end ofthe shank whereby a smokepassage is formed, and the outletofthe other passage being at the bottomof the shank whereby a cleaning passage is formed 5. As a new article ofmanufacture, a
